A vitamin C serum can be a useful addition to a routine built around cleansing, moisturizing and sun protection. The right choice depends on the formula, how it feels on your skin and how it fits with the products you already use. Explore our vitamin C and antioxidant serums, or ask the team at L&P Aesthetics Skin & Wellness for guidance.
What can a vitamin C serum do?
Vitamin C is an antioxidant. Depending on the formulation, a topical serum can help improve the appearance of uneven tone, dullness and fine lines while supporting protection against environmental free radicals. Results vary by product and individual skin.
A vitamin C serum does not replace sunscreen. Keep sun protection as a separate part of your routine.
Compare two vitamin C formulas
SkinCeuticals C E Ferulic
SkinCeuticals C E Ferulic combines 15% L-ascorbic acid, 1% vitamin E and 0.5% ferulic acid. SkinCeuticals describes it as a daytime antioxidant serum for visible signs of aging. Check the product details and directions before deciding whether it suits your skin.
Marini SkinSolutions C-ESTA Face Serum
Marini SkinSolutions C-ESTA Face Serum uses ascorbyl palmitate, a lipid-soluble form of vitamin C, alongside DMAE and hyaluronic acid. It offers a different formula and texture to compare with an L-ascorbic acid serum. The ingredient list includes fragrance, which may matter when choosing a product for sensitive skin.
How to fit vitamin C into your routine
Follow the directions for your particular serum. The amount, frequency and order of application can differ between products, so there is no single drop count that applies to every vitamin C formula. Follow with the other products and sunscreen recommended for your routine.
If you use prescription skincare, have very reactive skin or recently had a procedure, ask your treating clinician before adding or restarting a serum. A general skincare guide cannot replace your aftercare instructions.
Storage and changes in color
Follow the brand's storage instructions, keep the container closed and check its expiry or period-after-opening information. Color alone is not a reliable rule for every serum. SkinCeuticals specifically notes that C E Ferulic may change color without a loss of efficacy. If the product changes unexpectedly or you are unsure about your bottle, check with the manufacturer or your skincare provider rather than relying on a universal color test.
Common questions
Does vitamin C replace SPF?
No. See our sunscreen selection guide and sunscreen collection to compare sun-protection options.
Which vitamin C serum is best for me?
Compare the full formula, fragrance, texture and label directions, not just the vitamin C percentage. For help choosing, contact L&P Skin Shop and tell the team which products you already use.
